Problems solved by technology

Its disadvantage is that because the straight-through solenoid valve directly selects the channel through the spool, the spool needs to be in direct contact with the medium flowing through the valve, and the spring that controls the movement of the valve will also be in contact with the medium, so it is not resistant to chemical corrosion
Its disadvantage is that due to the limitation of structure, it is mostly used in two-way normally closed solenoid valves, and it is difficult to realize the function of three-way valves, and the processing of PTFE materials will greatly increase the cost of the product

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0038] figure 1 , figure 2 , image 3 , Figure 4 , Figure 9 , Figure 10 The first embodiment of the present invention (utility model) is shown.

[0039] This miniature double-diaphragm solenoid valve with fluid medium self-control equipment is assembled by an electromagnetic assembly 1 and a valve body assembly 2 . The electromagnetic assembly 1 consists of the valve sleeve 10, the through hole 101 provided at the bottom of the valve sleeve 10, the hollow iron stopper 12 extending out of the through hole 101, the lower spring 120 of the inner hole of the hollow iron stopper 12, and the lower spring 120 for adjusting the lower spring. The hexagonal countersunk head screw 121 of the deformation amount, the valve core 13 at the upper end of the hollow iron stopper 12, the electromagnetic coil 14 sleeved between the valve sleeve 10, the valve core 13 and the...

Abstract

A miniature dual-diaphragm electromagnetic valve with autocontroller of fluid medium is composed of an electromagnetic assembly and a valve body assembly. Said electromagnetic assembly consists of valve sleeve, hollow iron barrier, lower spring and its regulator, valve core, electromagnetic coil and electromagnetic end cover. Said valve body assembly consists of main valve body with 2 or more channels, upper and lower diaphragms, axial force-transferring rod, cover, elestic head for manual switch, and spring.

Description

technical field [0001] The invention relates to an automatic control device with a fluid medium, in particular to a miniature double-diaphragm solenoid valve. Background technique [0002] Most of the existing miniature solenoid valves are straight-through solenoid valves and single-diaphragm solenoid valves. [0003] The straight-through solenoid valve blocks the liquid flow (or air flow) passage by pressing and closing the valve core and the valve passage port, thereby realizing the three-way or two-way function. When two-way is realized, the valve has two valve channel ports. When energized and not energized, the valve core respectively presses the corresponding valve channel port to block the corresponding channel, which plays the role of channel selection. Its disadvantage is that because the straight-through solenoid valve directly selects the channel through the valve core, the valve core needs to be in direct contact with the medium flowing through the valve, and th...
